- Embryos being cultured for blastocyst transfer cycles (n = 648) were divided into three groups: (A) BL-T, blastocysts transferred, (B) BL-F, blastocysts.
- frozen and (C) PQ-D, Poor quality blastocysts/embryos failing to blastulate. Mean timings in BL-T and BL-F blastocysts(Group A, B) shown and compared to Group C. P value <0.05 was considered to be significant.
